Izicelo eziqhelekileyo
- Izibambo kunye nezibambo ezithambileyo– umgangatho obonwayo uxhomekeke ekubeni “akukho cala liqhekekayo” kwaye uzive uzinzile emva kokwaluphala.
- Iindawo zokutywina/zokunciphisa umswakama kwiindawo eziqinileyo– ujongano kufuneka lusinde ekucinezelweni, ekuphumleni, nasekutshintsheni kobushushu.
- Amaqhosha / iibhampa / iikona zokukhusela– iimpembelelo + uxinzelelo olujikelezayo lunokubangela ukukhula kwe-interface crack.
- Izinto ezinxitywayo/ezinxitywa ngabathengi– ulawulo lwe-warpage lubaluleke kakhulu njengokunamathela kwindibano kunye nezinto zokuthambisa.
Ukukhetha Okukhawulezileyo (I-Logic yoLuhlu olufutshane)
Khetha "iMechanical-First" xa
- I-substrate yiPP(okanye iindawo ezingenamandla aphantsi)
- Ukujikeleza kwe-thermal okanye ukuthembeka kobomi obude kubalulekile
- Ukungaphumeleli kokutsala/ukuxobula kwenzeka nasemva kokulungiswa kwenkqubo
- Ungongeza imingxunya/imingxuma/imisele ukuze uvale i-overmold
Khetha "I-Chemistry-Capable" xa
- I-substrate yiI-ABS(uhlala exolela ngakumbi)
- I-substrate yiPCkwaye uxinzelelo lwe-interface lulawulwa
- Uyilo lwenxalenye luthintela ukuvaleka okubonakalayo (imida yokuhombisa)
- Ungagcina ifestile yenkqubo ezinzileyo (ubushushu bokubumba + uqeqesho lokupholisa)
Qaphela: Eyona ndlela ilungileyo yokuthembeka okuphezulu idla ngokubaI-hybrid: inkqubo ye-interlock ephakathi nendawo + inkqubo ye-TPE ehambelanayo, endaweni yokuxhomekeka kwikhemistri yodwa.
Iindlela Eziqhelekileyo Zokusilela (Isizathu → Ukulungiswa)
Sebenzisa le theyibhile njengendlela yokufumanisa ngokukhawuleza. Kwi-overmolding, "uvavanyo lokuqala oluqinileyo lokutsala" aluqinisekisi ukuthembeka emva
uxinzelelo lokupholisakwayeimijikelo yobushushu-ukubanda.

Qaphela: Ukhetho lokugqibela luxhomekeke kwinqanaba le-substrate, ukugqitywa komphezulu, ubukhulu be-overmold, indawo yesango, uyilo lokupholisa, kunye nesicwangciso sakho sokuguga/sokushushu.
Iingenelo zoYilo oluPhambili (Indlela “eLungileyo” ebonakala ngayo)
- Ukucaca kwendlela yokuncamathela: uyazi ukuba uyatshixa, uyabophana, okanye zombini.
- Inkqubo eqaphela iimfazwe: uxinzelelo lokuncipha luphathwa njengotshintsho loyilo, kungekhona into emangazayo.
- Ukuthembeka kokujikeleza ngebhayisikile yobushushu: ujongano luhlala luzinzile ngaphandle kokukhula kwe-micro-crack.
- Ukunyamezelana kwenkqubo: iziphumo ezizinzileyo kuyo yonke ifestile ejikelezayo ngendlela efanelekileyo.
Ukucubungula kunye neengcebiso (Amanyathelo ama-3)
1) Qinisekisa indlela yokuncamathela
Gqiba nge-mechanical interlock vs chemical bonding (okanye hybrid) ngaphambi kovavanyo.
Oku kumisela iimpawu zenxalenye, icebo lesango, kunye novavanyo lokwamkelwa.

2) Lawula uXinzelelo lokuPholisa kunye nokuNciphisa
I-Warpage idla ngokuba yingxaki yokungalingani kokupholisa. Gcina ukupholisa kufana, kuphephe ukugquma okujiyileyo okunecala elinye,
kwaye uqinisekise ngenxalenye yokwenyani, hayi ngeekhuphoni.
kwaye uqinisekise ngenxalenye yokwenyani, hayi ngeekhuphoni.
3) Qinisekisa indlela echanekileyo
Musa ukuyeka xa uqala ukuxobula/ukutsala. Bandakanya ubushushu obujikelezayo, ukufuma/ukuguga kobushushu (ukuba kuyasebenza),
kunye nokulinganisa umthwalo wendibano kwi-interface.
kunye nokulinganisa umthwalo wendibano kwi-interface.
- I-PC vs ABS vs PP:baphathe njengeenkqubo ezahlukeneyo; musa ukusebenzisa kwakhona izinto ezifanayo.
- Uqeqesho lwe-Edge:uninzi lwezihlunu luqala emaphethelweni. Sebenzisa i-radii, kuphephe ukutshintsha okubukhali, kwaye ucinge ngokutshixa okuxutyiweyo.
- Uyilo lovavanyo:tshintsha inguqu enkulu enye kuphela ngokuphindaphinda (indlela, ulwakhiwo, okanye inkqubo), kungekhona yonke ngaxeshanye.
Ingaba eli phepha lilungele wena?
Uza kuzuza kakhulu ukuba:
- Ukugquma kwakhoiyaxobukaokanye ibonisa ukuphakama komphetho emva kwexesha elifutshane
- Uyabonaiphepha lokulwaemva kokupholisa okanye emva kweeyure ezingama-24–72
- Iinxalenye ziyaphumelela ekutsaleni kokuqala kodwa ziyasilela emva kokubaukujikeleza ngebhayisekile yobushushu
- Udinga isigqibo esicacileyo sendlela yokwenza izinto:ukudibanisa ngoomatshini ngokuchasene nokubopha ngeekhemikhali
